When a, B and C go shopping together, 1 / 2 of a's money is equal to 1 / 3 of B's money; 3 / 4 of B's money is equal to C's money How much did the three spend?

A 1 / 2 = B 1 / 3
A: B = 2:3 = 32:48
C 4 / 7 = B 3 / 4
C 12 / 21 = B 12 / 16
C: B = 21:16 = 63:48
A: B: C = 32:48:63
Each: 93 ÷ (63-32) = 3 (yuan)
Three people spent: 3x (32 + 48 + 63) = 429 yuan
